lCE-CREAMFREEZER.

SPECIFICATION forming part of Letters Patent No. 225,487, dated March 16, 1880,

Application filed June 26, 1879.

To all whom it may concern Be it known that we, JOSEPH E. PATTERJ soN and WILLIAM E. HAYES, of Erie, in the county of Erie and State of Pennsylvania, have invented a new and useful Ice-Cream Freezer; and we do hereby declare the fol lowing to be a full, clear, and exact description thereof.

Ou'r invention relates to that class of icecream freezers in which the cream-can is sustained and revolved within the outer vessel or tub, and in which no devices are used within the can for stirring the cream.

Our invention consists in improvements in the construction of such an ice-cream freezer, and are as follows: first, improved means for sustaining the can within the tub; second, improved means for adj nsting the can within the tub 5 third, improved means of attaching the crank-handle to the can 5 and, fourth, the resultant improved construction of the whole device.

Our invention is illustrated in the accompanying drawings as follows:

' Figure 1 is a top or plan view. Fig. 2 is a transverse vertical section on the line mm, Fig. 1. Fig. 3 is a top view of a portion of the can, and shows the means for keeping the cover in place.

The letters of reference indicate lows:

A is the tub or pail in which the freezer is placed. B is the can, and B is the cover. 0 is a metallic flange or rim, which is soldered to the can; and O is a friction-band, also soldered to the can. D D and D are irons, which are attached to the tub A, and have at th eirputer ends crescent-shaped arms for embracing and sustainingT, the can in a vertical position. Of these, D is made extensible by being made in parts with slots and clamped together by a set-screw, d. hold thefcan that it can revolve.

E is a handle attached to the cover B, and by it the can can be revolved.

F is the handle of the cover, by which it is lifted 0E of the can.

G is a lug on one of the stay-irons D, which laps over the flange O and holds the can down.

The rim is provided with a notch, c, which allows the lug G to pass the rim 0 when departs as folas near the edge as possible.

These stay-irons so encircle and band C is made of some soft metal, as of copper, and, like the ring (1, it encircles the can and is soldered to it. The object in having this band of soft metal is that as the can is revolved this band comes in contact with the circular arms of the stayirons, and, being of softer metal than these irons, it prevents noise. The object of the band is to prevent the stay-irons from wearing the tin of the can. Hence we call it a frictionband.

The cover B is also made of tin, and fits over the can, and reaches down toward the flange G. This cover is made to fit as close as possible, and yet be conveniently removable; and as the handle E, by which the can is revolved, is on the cover, it is necessary that the cover shall not slip around on the can. To avoid this an indentation, b', is made in the side of the can and a corresponding protuberance or lug is put on the inside of the .cover. (See Fig. 3.)

The handle E is attached to one side of the cover B, as follows: A cone-shaped piece of tin is firmly soldered to the top of the cover A bolt, 6, passes through this, and is firmly soldered to it and to the cover. This bolt extends up far enough to receive the handle E, which is generally of wood, and fits loosely on the bolt, so as to turn when held in the hand, as is common with crank handles. The handle E serves as a crank-handle by which to revolve the can in its bearings. The object of the cone-piece E is to stiffen and brace the handle.

The stay-irons D D D are made of cast metal, and are provided with screw-holes, so they can be attached to the tub. In attaching them they are placed so as to bring their arms against the friction-band C, so theirbearing will be against the band and not against the can. i

The object inhaving one of the irons, D, extensible is to enable the device to be adjusted that is to say, one casting may serve in place of the two by having longer encircling-arms. When the stay-irons are properly attached and the pivot-iron is in place the can may be set between the arms, the lug Gr passingthrough the notch 0. The can will then be seated on the pivot-iron P, and will be sustained in an upright position by the arms of the stay-irons, and the flange 0 being under the overlapping lug G, the can cannot rise up. When in this position. it can be revolved freely by the crank-handle.

What we claim is as follows:

1. In an ice-cream freezer, the combination, with the can B, of tub-irons D D D, having crescent-shaped arms, one of which is made extensible, so as to adjust the can to any eccentricity of the tub or to adjust the same ec centrically in the tub, substantially as and for the purposes set forth.

2. In an ice-cream freezer, the combination, with the cream-can B, of a cover, B, having a crank-handle, E, attached to one side thereof by means ofa bolt, 0, and conical bracingstay E, substantially as and for the purposes set forth.

3. An icecream-freezing apparatus composed of a tub, A, with stay-irons D D D- therein, one of which irons is provided with an overlapping lug, G, and which embrace a can, B, having a rin1,0, provided with a notch, 0, and a cover, B, which has attached thereto a handle, E, which is attached by means of a bolt, 0, and a bracing-stay, E, all being constructed and arranged to operate substantially as and for the purposes set forth.

In testimony whereof we, the said JOSEPH E. PATTERSON and WILLIAM E. HAYES, have hereunto set our hands.
